GRAND RAPIDS, Mich.—A new electrical steel from Arcanum Alloys, Inc., is designed to meet increased demand for high-quality electrical steels brought on by the electrification of the transportation sector and the infrastructure improvements needed to supply the corresponding demand for electric power. The steel technology and manufacturing company recently launched Opticore™, a new class of electrical steel alloys made using Arcanum Alloys’ proprietary Spatially Optimized Diffusion Alloying (SODA™) manufacturing technology, the company said in a release.

The Opticore series offers high-performance electrical steels at gauges from 0.002-inch to 0.010-inch (0.05-mm to 0.25-mm), for what the company called “the world’s most demanding applications.” The SODA technology is said to seamlessly integrate into the existing infrastructure of most steel mills and can be used to enrich the silicon and aluminum content of cold-rolled motor lamination steel, or low-carbon steel.  Products with SODA technology can be reduced in gauge after alloying, allowing for virtually any gauge steel to be used as a starting material, the release said.

The improving performance of motors, generators, and transformers in aerospace, medical, and power electronics applications is also expected to spur higher demand for high-performance electrical steels in the years to come, according to the release.

“This is an extremely exciting day for Arcanum Alloys and is the result of a rigorous development process executed with the speed that only the SODA platform allows,” said Dan Bullard, founder and CEO of Arcanum Alloys, in a statement. “This new grade of steel provides far superior performance to even the most advanced electrical steels currently on the market. Opticore will ultimately allow motors to deliver more operational hours with the same amount of power (i.e., battery size), or higher performance (i.e., torque) with the given amount of power.”

Arcanum Alloys ( is a materials startup backed by Khosla Ventures and Severstal Ventures.  The company was founded in 2011 with the mission to redefine how steel is produced using its patented SODA technology platform.
